Filed Oct. 14, 1959, Ser. No. 846,369 6 Claims. (Cl. 257-136) Thepresent invention relates to a radiator construction and it particularlyrelates to a radiator construction for hot liquid systems.

It is among the objects of the present invention to provide a simple,compact radiator system particularly designed for achieving maximum heatutilization with circulating hot liquids systems.

further objects and advantages will appear in the more detaileddescription set forth below, it being understood, however, that thismore detailed description is given by way of illustration andexplanation only and not by way of limitation, since various changestherein may be made by those skilled in the art without departing fromthe scope and spirit of the present invention. In accomplishing theabove objects it has been found most satisfactory, according to oneembodiment of the present invention, to provide a fin construction inwhich the pipes extending through a series of parallel, closely spacedfins will be so arranged as to be conveniently located in recesseswithin the wall of a room or along the side of the wall without undue oruneconornical space consumption.

It has been found, according to the present invention, that, with oneheader outlet and return,'connections may be-readily made with assuranceof maximum utilization and circulation of the hot liquid in its passagefrom the furnace and back to the furnace.

Desirably a series of parallel horizontal pipes are positinned-in a wallrecess which may be insulated from the rear so that full heat reflectionwill occur forwardly into the room space.

The units consisting of a plurality of fins, the spaces between whichare closed by in-turned flanges, may be positioned with their frontedges in or along the plane of the wall. The inlet and outlet connectionto each radiator series is achieved by having pipes in the main headerfacing the direction of flow and away from the direction of flow so asto create a forced flow through the radiator sections themselves. I

With the foregoing and other objects in view, the invention consists ofthe novel construction, combination "and'arrangement of parts ashereinafter more specifically described, and'illustrated in theaccompanying drawings, wherein is shown an embodiment of the invention,but it is to be understood that changes, variations and modijficationscan be res'ortedto which fall within the scope of the claims hereuntoappended.

In the drawings wherein like reference characters def notedcorresponding parts throughout the several views:

. FIG. 1 is a side diagrammatic elevational view illustrating theconnection between the radiators and the main headers.

' "FIG. 2 is a transverse sectional view indicating how the radiatorunit may be' inserted in the wall of a room or other enclosure.

Refering to FIG. 1, there is shown the main flow pipe r 2 A carrying theheated liquid which may be of light or medium bodied oil, with thebranch connections B as an inlet and C asan outlet to the variousradiator sections C, D E and F which are inserted in the wall structureG.

Each radiator section C, D, E and P has alhorizontal main pipe or tube Hwith a plurality of radiating fins I and with the inlet connection K andthe outlet connection L respectively. l g The units are held in positionby means of the spring clips or resilient members M which extendinwardly from the wall sections N. The radiator unit has a back casing Pand a front closureframe Q.

Referring to the main flow pipe A, which may be positioned between thewalls or between the ceiling and floor, the hot oil is caused to flow inthe direction 10 under pump pressure from a furnace.

At the inlet connection B the end of the tube, as

indicated at 11, faces the direction of the oil flow and has a slightenlarged bell-shaped mouth 12, with the result that oil will be forcedat 13 into the curved inlet neck B. At the other side there will be anend portion 14 extending in the direction of flow and. the hot liquidwill be drawn out, as indicated at 15, through the curved outlet necksection C. Both units B and C are joined into the pipe A by the strongconnections 16 and 17.

The piping B connects to the end header K, which extends through the endportions 18 of the horizontal tubes H.

There are flow connections as indicated at 19 adjacent the top of thepipe H. Similar connections are provided at the outlet side L, whichalso extends through the ends 20 of the headers H. Here, too, theopenings 21 are positioned at the top. V

The fins I, which may be closely spaced and parallel to each other, aremounted upon each tube H and may be soldered thereto at their centralportions. The spring clipsv M, which are bolted, riveted or screwed at22 at their lower ends 23, have upper bifurcated sections '24 which fiton to and hold the pipe sections H in position.

Each tube H may be provided with the locator members N atthe endsthereof. As shown in FIG. 2, there are four horizontal tubing sections,each having upper circular openings eccentrically disposed, as indicatedat 19 in FIG. 2. V The fins I are spaced apart by the spaces 35, and, ifdesired, their front ends maybe flanged in one direction so as to closethe spaces 36 between them and give maximum radiating surface. I

The open portions, as indicated at 37 andj38, permit the air to passin,'as indicated at 39, and pass out, as indicated at 40, to givemaximum radiating effect.

The frame Q may carry anornamental grill and the back plate or casing Pmay be made of sheet steel or of other metal material, preferably withan interiorly polished face, as indicated at 41.

Desirably the fin length will terminate inside of the headers K and L,with the ends of the pipe projecting adjacent to but not touching thewall sections N so as to leave space for expansion. 1

The entire unit is very compact and the varying number of sections maybe employed from one horizontal pipe'H tofouror more horizontal pipes H.

The fins should extend the full width of the recess, as indicated at Pin the wall, and they may be made or]? square or aluminum sheet spacedone inch apart and 2% inches square.

The piping H may be copper piping outside diameter, with wall thicknessand the openings 19 may be 1 in one preferred construction.

The upper ends of the vertical members K and L are plugged, as also arethe ends of the horizontal tubes H.

The inlet and outlet connections, as indicated at B and C, will give aVenturi tube efiectand will assure a forced flow of hot oil or otherliquid through the radiators consisting of the horizontal pipes H andthe fins I.

The system will be most effective in heat utilization and may beconveniently installed, particularly with hot oil systems.

As many changes could be made in the above radiator construction, andmany widely difierent embodiments of this invention could be madewithout departure from the scope of the claims, it is intended that allmatter contained in the above description shall be interpreted asillustrative and not in a limiting sense.
